The quantum Hall effect (or integer quantum Hall effect) is a quantized version of the Hall effect which is observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, in which the Hall resistance Rxy exhibits steps that take on the quantized values.

L'effetto Hall quantistico è l'equivalente quantistico dell'effetto Hall (che prende il nome dal fisico Edwin Hall). L'effetto Hall quantistico è osservato in sistemi elettronici bidimensionali ad alta mobilità e basso disordine.
1 lug 2020 · Why the Hall conductance is quantized was an open problem in condensed matter theory for much of the past 40 years. Spyridon Michalakis who worked on the solution — published in 2015 — gives a...
3 feb 2015 · The quantum Hall effect has led to a deeper understanding of topological (or geometrical) effects in physics. It is related to buzzwords like Berry phase, Chern numbers, topological phases,...
